IMPROVEMENT IN MACHINES FOR NAlLlNG BOXES.

Specification forming part of Letters Patent No. 414,929, dated November1864.

To all whom it may concern.-

Be it known that we, 0. BAUER and \V. G. MUNDER, both of Newark, inthecounty of Essex and State of New Jersey, haveinvented a new andImproved Machine for Nailing Boxes; and we do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming apart of thisspecification, in which Figure 1 represents a longitudinal verticalsection of our invention. Fig. 2 is a transverse vertical section of thesame, taken in the plane indicated by the line 99 00, Fig. 1. Fig. 3 isa detached plan of the nail-driver. Fig. 4 is a detached elevation ofthe mechanism for depressing the carrying-belt.

Similar letters of reference in all the figures indicate correspondingparts.

This invention consists in the employment or use of a rotatingnail-carrier in connection or combination with a reciprocatingnaildriver, and with a gage or other equivalent device to hold theboards or box to be nailed in position in such a manner that the nailsintroduced into the carrier are successively brought opposite saidboards or box, and one alter the other is driven into the wood at theproper intervals. The nail-d river is provided with a shoulder, so thatthe nails are first driven partially into the wood, allowing them to bewithdrawn from the carrier, and that they are finally driven home by thefinishingface of the nail-driver. The boards or boxes to be nailed arearranged on a table and held in position by an adjustable gage, and theyare fed automatically by a reciprocating feeding mechanism, which can beadjusted according to the desired distance of the nails one from theother.

A represents a frame made of metal or any other suitable material, andsecured down to a bed-plate, B, or to the ground. Said frame supportsthe two standards 0 O, which form the rigid bearings for the pivots aa,on which the wheels D D rotate freely. These wheels are connected bya-belt, E, and the standard 0, which supports the pivot of the wheel D,is hinged and arranged so that it is rendered yielding, and that thebelt can be readily depressed to make room for the nail-driver, as willbe presently explained. A spring, b,

has a tendency to pull the standard 0 in the direction of the arrowmarked near itin Fig. 2, so that the belt is always exposed to therequisite strain.

The wheel D is that part of our machine which we term the nail-carrier.It is provided with a series of notches, 0, corresponding in size andshape to the shank of ordinary nails, such as are generally used fornailing boxes. For nails of different size the size of the notches hasto be altered. An intermittent rotary motion is imparted to this wheelby the action of a spring-pawl, d, which is hinged to the pivot q, andto which an oscillating motion is imparted by a crank, e, with which itconnects, as clearly shown in Fig. 2. Said spring-pawl engages with theteeth of a ratchet-wheel, j, which is cast solid with or otherwiserigidly connected tothe nailcarrier D. The crank e is mounted on the endof a shaft, 9, which has its bearings in suitable boxes on the side ofthe frame A, andto which a rotary motion is imparted by asuitablebevelgear from the driving-shaft h, or in any other desirable manner.The nail-carrier D works in close proximity to the shield E, which is soarranged that the nails cannot be pushed back into the notches anyfarther than desirable. The nails on being introduced into 1 the notchesc of the nail-carrier are held inpo sition by the belt E, and as thesaid carrier rotates in the direction of the arrow markedthereon in Fig.2, the nails are successively carried down in front of the hammer ornaildriver F. This nail-driver is guided by suit= able ways in the frameA, and a reciprocating motion is imparted to it by a crank, t, in thedriving-shaft, connecting with it by the pit= man j, or in any othersuitable manner.

The face of the nail-driver is formed with a shoulder, R, as clearlyshown in Fig. 3, and as the same comes forward the lowest part of itsface strikes the head of the nail in the notch, which at that moment isin its lowest position, and the point'o f the nail is driven into theboard placed behind the shield E. As soon as this nail has thus beenfastened in the board, the feed mechanism carries said In order to allowthe nail-driver to act on the nails without coming in contact with thebelt, the lower section of said belt passes through a loop, Z. attachedto the horizontal arm at of a bell-crank lever, m a, and a camlever, 0,which is acted upon by a tappet, p, projecting from the lower surface ofthe naildriver, strikes the vertical arm a of the bellcrank lever anddepresses its horizontal arm, together with the section of the beltpassing through the loop Z. In order to render this depression of thebelt practicable, it is neces sary that the-bearing of the wheel D shallbe made yielding, as above described.

The boards or boxes to be nailed are fed to the machine on the table orplatform H behind the shield E, and they are held in position by anadjustable gage, I. They are fed along automatically on this table-bythe feed mechanism, which consists of two (more or less) prongs, g,which project upward through slots in the table from a slide, q, towhich. a reciprocating and rising-and-falling motion is imparted by thecombined action of cams 1" r and a spring, s. On being pushed upward bythe action of the cam a, the points penetrate the wood and cause thesame to move forward on the table for the desired distance. Thisdistance, or theamount of feed, depends upon the length of the intervalsatwhichthe nails are to be driven, and,it is adjusted by ascrew,t,similar to the feed ofa sewing-machine. It is obvious, however,that the construction of the feed mechanism can be changed in yariousways, and we do not wish to confine ourselves to the previous mechanismshown in the drawings.

By this machine the operation of nailing boxes can be performed almostentirely automatically. It requires one boy or girl to feed the nails tothe notches of the nail-carrier, and another one to place the boxes tobe nailed in the proper position on thetable H. The nails are driven asfast as the same are supplied to the carrier.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is

1. The employment or use ofa rotating nailcarrier in combination with a'reciprocating nail-driver, and suitable table supporting the boards orboxes to be nailed, substantially in the manner and for the purposespecified.

,4 2. Making the nail-driver with a shoulder, 7c,substantially as andfor the purpose set forth.

3. Depressing the belt E by the automatic action oi" the machine,substantially as and for the purpose described.

4. The automatic feed mechanism, in combination with the nail-carrierand nail-driver, constructed and operating in the manner and for thepurpose substantially as herein specified.
